Step-by-step explanation:

Answer:

2

Step-by-step explanation:

combine like denominators:

(1-x^4)/(x^2+1)+(x^4-1)/(x^2-1)

factor:

(1-x^2)(1+x^2)/(x^2+1)+(x^2+1)(x^2-1)/(x^2-1)

reduce:

(1-x^2)+(x^2+1)

1+1=2

Answer:

Fred = 31

Natalie = 15

Step-by-step explanation:

We have Natalie and Fred's whos age are unknown, we know that when added, their ages equal 46. While when multiplied with Natalie's age 4 times, their ages is 91.

Create two systems :

F = Fred

N = Natalie

F + N = 46

4N + F = 91

We can change the first equation to Natalie's age alone :

N = 46 - F

Now substitute this into the second equation :

4(46 - F) + F = 91

Distribute :

184 - 4F + F = 91

Subtract 184 from both sides :

-4F + F = -93

Add like terms :

-3F = -93

Divide -3 from both sides :

F = 31

Therefore, Fred is 31 years old. Now replace his age in the first equation :

31 + N = 46

46 - 31

15

Therefore, Natalie is 15 years old.

pls give thx and brainliest

Answer:

A)

45% of customers were not satisfied with the graphics.

B)

22,500 people are expected to not be satisfied with the graphics.

6,500 people are expected to have no opinion.

C)

The majority of people are unsatisfied with the graphics.

Step-by-step explanation:

The company polled 1,000 out of the 50,000 people who had purchased the program.

42% was satisfied with the graphics.

And 13% had no opinion.

Part A)

When totaled, those satisfied, unsatisfied, and with no opinion should be 100%.

Since 42% are satisfied and 13% have no opinion, this leaves 100 - 42 - 13 or 45%.

So, 45% of customers were not satisfied with the graphics.

Part B)

Since 45% of the polled were unsatisfied with the graphics, 45% of the total 50,000 can also be expected to not be satisfied.

45% of 50,000 is 0.45(50000) = 22500.

So, 22,500 people are expected to not be satisfied with the graphics.

Likewise, 13% had no opinion.

So, 13% of 50,000 is 0.13(50000) = 6500.

6,500 out of the current 50,000 customers are expected to have no opinion with the graphics.

Part C)

Since the majority of people are unsatisfied with the graphics (45% > 42%), it is reasonable to create a new version with improved graphics.

Answer:

false

Step-by-step explanation:

you have to order them from least to greatest in order to find the answer

Answer:

Let's solve for x.

4x+5y=7

Step 1: Add -5y to both sides.

4x+5y+−5y=7+−5y

4x=−5y+7

Step 2: Divide both sides by 4.

4x/4=−5y+7/4

x=−5/4 y+ 7/4

Answer: for the first one x=−5/4 y+ 7/4

3x−2y=−12

Step 1: Add 2y to both sides.

3x−2y+2y=−12+2y

3x=2y−12

Step 2: Divide both sides by 3.

3x/3=2y−12/3

x=2/3y−4

Answer:

x=2/3y−4

Answer:

Using distributive property is the next step in solving the equation

Step-by-step explanation:

-2(4x-1)-7=5

-8x+2-7=5

Answer:

The next step would be to do distributive property.

Step-by-step explanation:

-2(4x-1)-7=5

-8x + 2 - 7 = 5

-8x - 5 = 5

     +5    +5

-8x = 10

/-8     /-8

x= -5/4

 or

x = -1 1/4

Answer:

c= 5-ab

Step-by-step explanation:

Ive done this answer

8 and 1 are alternate exterior angles.

Answer:

<8 and <1

Step-by-step explanation:

<8 and <1 are both outside of the parallel so they are exterior and opposite to each other which is alternative exterior.

Hope this helps, thank you !!

Answer:

   here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).

   Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.

   Now, it is time to calculate the probability.

   The required probability is,

   p = (No. of cases favorable for the event)/(Total no. of cases)

   =6/36 =

Step-by-step explanation:

Two fair six-sided dice are rolled. What is the probability that the sum of the two dice is seven?

Answer:

i^0 = 1

i^1 = i

i^2 = -1

i^3 = -i

i^4 = 1

i^5 = i

i^6 = -1

i^7 = -i

i^8 = 1

i^9 = i

Step-by-step explanation:

Anything raised to 0 is 1

Anything raised to 1 is itself

I just always knew i^2 = -1

I put this rest into the calculator honestly

But if you look at the stuff from i^2, you'll notice there's a pattern (-1, -i, 1, i) and it repeats. I bet if you raise i to the 10th, 11th, 12th, and 13th power, it is going to repeat the same pattern. I hope this helps in any way.

Answer:

I dont know but maybe later

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1

Answer:

12.0 cm

Step-by-step explanation:

✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.

BC² = 10² - (9 -3)²

BC² = 10² - 6²

BC² = 64

BC = √64

BC = 8 cm

✔️Find AC using Pythagorean Theorem:

AC² = AB² + BC²

AC² = 9² + 8²

AC² = 145

AC = √145

AC = 12.0415946 ≈ 12.0 (3 significant figures)
